Information for returning pumps
In the current situation of heightened concern over the handling of hazardous materials, any equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to health must be decontaminated before it is returned to Watson-Marlow or its distributor.
A certificate (a suitable blank form is included at the rear of these operating instructions), or signed statement, must be attached to the outside of the shipping carton.
This certificate is required even if the pump is unused. If the pump has been used, the fluids that have been in contact with the pump and the cleaning procedure must be specified along with a statement that the equipment has been decontaminated.
Safety
In the interests of safety, these pumpheads and the tubing selected should only be used by competent, suitably trained personnel after they have read and understood this manual, and considered any hazard involved.
Any person who is involved in the installation or maintenance of this equipment should be fully competent to carry out the work. In the UK this person should also be familiar with the Health and Safety at Work Act.
There are dangerous voltages (at mains potential) inside the unit. If access is required, isolate the pump from the mains before removing the cover.

Recommended Procedures
DO keep delivery and suction lines as short as possible.
DO use the minimum number of bends in rigid pipe runs. If there must be a bend, use a swept bend and not a tight elbow.
DO use suction and delivery pipelines with a bore equal to or larger than the bore of the tube fitted in the pumphead. When pumping viscous fluids, the losses caused by increased friction can be overcome by using pipe runs with a cross sectional area several times greater than the pumping element.
DO run at a slow speed when pumping viscous fluids. When using the 501RL pumphead, a 4.8 or 6.4mm bore tube with a 1.6mm wall will give best results. Tube smaller than this will generate a high friction pressure loss, so reducing the flow. Tube with a larger bore will not have sufficient strength to restitute. Flooded suction will enhance pumping performance in all cases, particularly for materials of a viscous nature. Silicone and Marprene tubing is available with a 2.4mm wall thickness for speeds up to 200rpm. (The rotor will require re-setting to a roller/track gap of 3.8mm.)
DO use the largest possible bore tube running at slow speed for the longest tube life.
DO fit an extra length of pump tube in the system so that you can move the tube through the pumphead occasionally, without needing to break the pumping circuit. This is particularly useful for extending tube life in long running sterile applications.
DO keep the track and rollers clean, and ensure that the rollers are free.
DO NOT fit valves in the suction or delivery lines without considering that peristaltic pumps are self priming and will hold their prime up to several metres, so there may be no need for non-return or foot valves, nor for the loading valves required on many other kinds of pumps.
Any valves fitted must cause no restriction. If electrically actuated valves are fitted, they should be interlocked so that the pump will only run when the valves are open. Fit an automatic by-pass if manual valves are installed.
When using Marprene or Bioprene tubing, after the first 30 minutes of running, re-tension the tube in the pumphead by releasing the tube clamp on the delivery side a little and pulling the tube tight. This is to counteract the normal stretching that occurs with Marprene and Bioprene, which can go unnoticed and result in reduced tube life.
Tube selection The chemical compatibility list published in the Watson-Marlow catalogue is only a guide. If in doubt about the compatibility of a tube material and the duty fluid, request a tube sample card for immersion trials. Remember the sample will be fully immersed, but the fluid when in use will only be in contact with the inside of the tube. If the material swells but does not lose its strength it could be worth considering.
Viscous dispensing To overcome the common problems of reduced accuracy and dripping delivery pipes, the suction and delivery lines should be kept as short as possible. Use larger bore transmission tubing than that in the pumphead to keep the friction losses to a minimum. Improvement will be noticed if rigid or semi-rigid pipe is used on the delivery side. The rigid tube is effective in reducing over-run because it does not expand during pumping.

Part 1: 505Dz Drive
Siting
To ensure correct lubrication of the gear box it is important to run the pump only Installation while its feet are standing on a horizontal surface.
It should be situated where there is free air to circulate around the pump and where the tubing is allowed to enter the tube clamps without kinking.
The 505Dz can be operated at ambient temperatures from 5C to 40C. Storage temperatures from -40C to 70C are permissible, but allow time for acclimatisation before use.
Electrical connection
The 505Dz operates on single phase mains electricity supplies only. It is fitted with a mains voltage selector which must be set to either 120V for 100-120V 50/60Hz supplies or 240V for 220-240V~50/60Hz supplies. For sites where the local voltage is below this specification and the pumphead loading is high, refer to Part 4: Reduced voltage operation.
A mains cable fitted with a moulded plug is supplied with the pump, but if another plug is to be fitted, the colour coding of the mains lead must be observed. The mains cable for 220-240V supplies is coded so that the live lead is coloured brown, the neutral lead is coloured blue, and the earth lead is coloured green and yellow. The mains cable for 100-120V supplies is coded so that the live lead is coloured black, the neutral lead is coloured white, and the earth lead is coloured green.
Should the pump fail to operate, check that mains electricity is available at the unit, that the voltage selector switch is in the correct position, that the fuse is intact and that the pump is not stalled by incorrect fitting of tubing. If the pump is to be used under manual control and fails to operate, check that the manual mode has been selected. If the pump is under auto control check that there is a signal, the connections are correct and that the pump is correctly set up.
There are dangerous voltages (at mains potential) inside the unit. If access is required, isolate the pump from the mains before removing the cover.

Failure to operate

For higher accuracy, use smaller bore tubing. However this will also increase filling time.
For faster filling time increase tubing bore size. However this will decrease accuracy.
All tubing will show a gradual drift in the dosed volume, which can be corrected by recalibration. For minimal drift use Silicone tubing (if chemically compatible).
The results seen on page 6 were obtained using Silicone tubing pumping water at zero suction and delivery pressure, with a 501RL pumphead at 300rpm over at least 50 doses. It is intended as a guide only.
It is advised to carry out trials under operating conditions to determine a satisfactory compromise between dose time and accuracy. The important factors are suction and delivery pressures, temperature, and fluid viscosity.
Flow rates
The 505Dz is fitted with the 501RL pumphead. The flow rates given below were obtained using silicone tubing, with the pumphead rotating clockwise, pumping water at 20C with zero suction and delivery pressures (unless otherwise stated). Where an application is critical, the flow rate should be determined under operating conditions. The important factors affecting flow rates are delivery pressures, temperature, and fluid viscosity. Tube life will be reduced when pumping against pressure.
